About OneStep.tools

Small, honest tools that respect your data and your time.

What is OneStep.tools?

OneStep.tools is a collection of free utilities for everyday tasks: counting words, splitting bills, converting units, making invoices, generating passwords and more. Every tool runs entirely in your browser. There is no server processing your input, no account to create, and nothing to install.

Principles

Private by design. Whatever you type into a OneStep.tools tool is processed on your own device and is never uploaded. Tools that remember anything (like the invoice generator) use your browser’s local storage, which you can clear at any time. See our privacy policy for the details.

Fast and free. Pages are lightweight and work offline once loaded. All tools are free, with no sign-up walls.

Honest about money. The site may display advertising or affiliate links to cover its costs. They are clearly separated from the tools, and never in the way of using them.
